  • Abstract
    Wavelength modulation waveforms were studied in tunable diode laser photoacoustic spectroscopy by way of simulations and experiments. The modulation waveforms were sinusoidal, triangular, shaped, and quasi-square waves. The quasi-square waveform gave the largest signal-to-noise ratio.
